Standstill periods

WARNING!
Protect the pump from frost.
If the pump is to remain idle for a long period of time, it must be completely emptied as
described below:
1. Set the regulating valve in the by-pass position.
2.
Allow clean water to circulate around the pump for a few minutes. Mix an antifreeze
liquid with the clean water if there is a risk of freezing.
3. Allow the pump to suck up air until all the liquid it contains has been emptied out.
Periodically (at the end of each operating season) inspect the pump and the components of
the system (hoses, pipe fittings, connections, etc.).
Replace all components that show signs of wear.
